how to prevent iOS safari alert when trying to open non-installed native app?

Question

I\'ve been looking for a way to open a native iOS app from the browser. I found a decent solution here: Is it possible to register a http+domain-based URL Scheme for iPhone

Answer 1

For me this does the job:

window.open(appLink, '_system')`

window.open(appstoreLink, '_system')

Works for android and ios. If the first one can't be opened the second one is called without alert or something. Otherwise it just opens the app.
